Keeping things moving!

Innovation is our drive - this principle marks BRECO Antriebstechnik Breher GmbH & Co., manufacturer of BRECO® and BRECOFLEX® timing belts as the most innovative producer in the field of polyurethane timing belt technology worldwide. The basis for a high-quality and reliable product is provided by wear resistant polyurethane for the belt body and high tensile steel cord tension members.

The name BRECO became the synonym for polyurethane timing belts resulting from years of experience in the field of thermoplastic polyurethane, the development of BRECO® and BRECOFLEX® manufacturing processes and their further development. The BRECO® and BRECOFLEX® timing belts, the pulleys designed to match them perfectly, and other com-ponents supplied by BRECO reflect the breadth of experience gathered over decades by countless people who have used the products. We maintain a consistently high level of quality through our exclusive use of high-quality materials and by listening to feedback from our suppliers about the needs of our customers.

One strong point is the development and production of special belts for various application fields. The large number of belt coatings and the most varied shape of flights open up an extremely broad application field for BRECO® and BRECOFLEX® timing belts. We stock a broad range of belt and tension cord materials to cater for applications in very cold or very hot environments.

In simple applications too, BRECO® timing belts offer all the advantages and quality expected of a high-end branded product. Safety, durability, accuracy and availability are some of the benefits which ultimately have a positive impact on costs.

All our products conform to the European RoHS Directive which restricts the use of hazardous substances.

Preferred

running directionCurved teethAs a logical consequence of the demand for reducing running noise, a profile was developed which does without the conventional polygon effect. In addition to smooth running, the profile has, in comparison to the AT, a larger tooth face and is self-guiding in the preferred running direction.Preferred use:• Special demands regarding smooth running properties and transmission precision• Tight assembly dimensions • Transport and transmission tasks

AT high capacity profileFurther development of the T profile resulted in the AT profile. This type of belt is characterised by the larger tooth shear strength resulting from the larger tooth volume and the stronger tension members.Further advantages:• Favourable tooth mesh• Strengthened tension members for constant pitch• Improved performance up to 50 % as compared to the T profile• Precise transmission of movement in conjunction with synchronous pulleys with reduced or zero backlash• Reduction of meshing impacts or shocks

Curved teeth with guiding trackThe BATK has ensued from the BAT. The timing belt is self-tracking in both running directions due to the integrated guiding track.Preferred use:• Special demands regarding smooth running properties and transmission precision• Applications in the field of the linear and power transmission technology• Tight assembly dimensions

AT in DL versionThe DL timing belt (the belt is double-sided) is applied in the power transmission and transport technology. Multiple-shaft drives with different rotational directions can be realised with this timing belt. Full loadability on both tooth sides.

For special areas of use we can produce all types of timing belts in materials, whose properties make it possible, to use belts in following areas:• Foodstuff sector (TPUFD)• Low temperature range from -30°C to +5°C (TPUKF)• High temperaure range from +20°C to +110°C (TPUWB)• Use in low aggressive environment (TPUAU)

As alternative to the standard steel cord tension members, tension members in stainless steel and aramide are available. In the case of strong bending stress resp. tension load, timing belts with high flexible tension members (E) resp. with reinforced tension members could be produced.

For further information about the resistance of polyure-thane timing belts and available belt materials as well as alternativly tension member materials please contact our distribution partner.

Construction

BRECO®, BRECOFLEX® timing belts are manufactured of wear resistant polyurethane and high tensile steel cord tension members. Both high quality materials combined form the ba-sis for dimensionally stable and high resistance polyurethane timing belts. Polyurethane timing belts have a very high span rigidity. No post-elongation of the tension members is to be expected in continuous operation. Only under extreme load and after a short run-in time, the pre-tension of the belts might slightly reduce by the tension members settling, ma-king a once-only re-tensioning of the timing belt unavoidable.

The timing belts are temperature resistant with ambient temperatures from -30°C to +80°C. Applications close to the limit temperatures (<-10°C and >50°C), however, might require adapted dimensioning. For specific temperature ranges various belt materials are available. Please contact our distribution partner for this type of application.

The production methods according to which BRECO®, BRECOFLEX® timing belts are produced, allow keeping within tight tolerances which guarantee a uniform load distribution during power transmission. These polyurethane timing belts are suitable for the transmission of high torques as well as the precise positioning and transport of various goods.

ATP high capacity profileFurther increased performance, noise reduction and extension of the belts useful life led to the development of the ATP timing belt. The basic concept of the ATP profile provides the division of the trapezoidal tooth into two individual and load bearing teeth. Performance increase up to 60 %, running noise reduced by up to 10 db(A) and an increased longevity by:• Tooth surface area increased by 70 %• Uniform load/tension distribution• Improved power dispersion• Reduced polygon effect• Small construction width• Optimised tooth mesh

ATNThe ATN timing belt is especially designed for the application in the transport technology. The flight fastening system in the belt tooth permits fast fitting and replacement of the flights individually manufactured for the conveying appli-cation concerned.

ATN with V-grooveThe ATN timing belt is especially designed for the application in the transport technology and applied where no flanges on the pulleys and other guiding elements are possible for constructional reasons.

Offset teethAT performance profile with two toothed tracks with a belt designed as SFAT. These toothed tracks are offset by half a tooth pitch in relation to each other. In combination with the accompanying synchronous pulleys, the SFAT is self-guiding. No flanges are required.Preferred use:• Running on synchronous pulleys without flanges• Where low noise is of the essence (reduced polygon effect)

Imperial profileImperial pitches according to DIN/ISO 5296 are available in the following sizes: XL = 5,000 mm L = 9,000 mm H = 12,000 mm XH = 22,000 mm Preferred use:• Applications in imperial units

Self-tracking beltsSelf-tracking belts are a combined construction of synchro-nous belts and V-belts with straight running characteristics. The performance range is that of the standard T or AT profiles minus the non toothed belt width.Preferred use:• Where large lateral forces apply• Running on synchronous pulleys without flanges

(Also available in TK-version)

Standard profileThe timing belt with a trapezoidal profile according to DIN 7721 is regarded as the classical standard timing belt.Preferred use:• For standard drive tasks • For high bending stress

Application informations: For intended application under extreme conditions please contact our technical department for advise.

Steel cord tension members (Example):

The thinner the individual wire the more flexible the whole timing belt.

For further information about the resistance of polyurethane timing belts and available belt materials as well as alterna-tivly tension member materials please contact our distribution partner.

The thinner the single wire, the more flexible the overall tension member! This interrelation led us to develop BRECO® and BRECOFLEX® timing belts with E tension members.

In the E tension member the tension member cross-section is distributed to a lot more thin individual wires and, therefore, the bending fatigues are markedly lower in the individual wires. The advantage of the E tension members is a higher flexibility. This is especially important, when smaller mounting dimen-sions for pulleys and tension rollers are required. The minimum number of teeth and/or minimum diameter of the pulleys can be fallen below up to 30% compared with standard tension members.Timing belts with E tension members are recommended for multi-shaft drive with frequent bends.

Summary:

• Thinner individual wires in the steel cord• Higher dynamic capabilities• Extremely high bonding and bending fatigue strength• Smaller pulley and tension roller diameter• No correction of the synchronising pulleys are necessary

Timing belt guide of the BAT timing belt

The BRECO® and BRECOFLEX® timing belts with curved teeth have only one preferred running direction. In this direction the convex side of the tooth curve points in running direction of the drive. When observing this running direction the teeth laterally guide the belt also with large span lengths for which reason flanges are not required.

Even if the pulleys, tension and return rollers as well as their axes are perfectly aligned, we recommend a minimum span length of 5 times the belt width (see graphic) between the elements. This results in reduced lateral forces and the respective friction.

If tension and return rollers running on the teeth have a distance to their upstream pulley or roller exceeding 5 times the belt width (b), these rollers should be designed with teeth. If these elements are running on the back of the belt without teeth, flanges must be used (see graphic). Both measures lead to a better belt guidance and result in a high running performance.

BATK timing belts

For the BATK timing belt guidance by flanges is not required due to the teeth design. A wandering-off effect from the pulleys is excluded due to the guiding track.

Application fields

The BRECO® and BRECOFLEX® timing belts type BAT are sui-table for all areas of the power transmission and transport technology, where high transmission precision, low variation tendency, smooth running and only one running direction are required. The BAT timing belt is self-guiding in its preferred running direction, thus, no guiding elements are required.

The BATK timing belt is mainly designed for application in the linear and power transmission technology.

BAT / BATK timing belts

„New profile shapes result in improved performance features“, this comment often describes the development possibilities of polyurethane timing belts. The curved tooth based on the proven AT profile forms the basis for the new BRECO® and BRECOFLEX® timing belts with curved teeth. The unique curved teeth guarantee notably improved transmission and running properties. On the one hand the BAT tooth has an increased load bearing capacity, on the other hand it does not abruptly run into the pulley gap but perfectly timed. Both features combined lead to an increased performance, clearly reduced running noise as well as a higher transmission precision and a lower vibration tendency. The belt centers itself on the pulleys in the stated preferred running direction due to the curved shape of the tooth which produces the self-guiding effect.

The BATK timing belt has ensued from the BAT timing belt. Compared to the BAT the BATK is provided with a guiding track resulting in a timing belt self-guiding in both running directions.

The special characteristics

• Increased tooth load resulting from the tooth curve

• Clearly reduced running noise due to a time elongated tooth mesh

• Higher power transmission precision and lower vibration tendency due to a reduced polygon effect

• The BAT is self-guiding in the preferred running direction, no flanges are required

• The BATK is self-guiding in both running directions due to the integrated guiding track making flanges obsolete

• Length constant belts due to the application of high tensile steel cord tension members

Materials

BRECO® and BRECOFLEX® timing belts are manufactured according to standard in the material with the designation TPUST1 and steel cord tension members. Other materials e.g. for low or high temperature or for contact with food are possible. Likewise high flexible tension members (E) and ten-sion members in stainless-steel are available. Our distribution partner advises you regarding our possibilities.

BRECOFLEX: The BRECOFLEX® timing belt is manufactured in endless lengths without tension member interruption. The tension member is spirally coiled. BRECOFLEX® timing belts are universal applicable for all tasks in the drive technology up to 10000 min-1.

Application areas

Endless timing belts for power transmissionsAll drives designed for a high performance should preferably be produced as BRECOFLEX® timing belts with a full length steel cord tension member. They can be subjected to both permanent operation or for a start-brake characteristic. They operate in a rotational speed range of up to 10000 min-1.

Endless timing belts are available in preferred catalog lengths. Our production range also permits the supply of intermediate lengths up to a maximum endless length of 20000 mm.

StandardPlus - BRECOFLEX® timing belts with improved properties

The new generation of BRECOFLEX® timing belts was special developed for high precision positioning applications. The use of the bifilar winding reduces the tendency of the belt to run off. The special way of winding prevents the formation of lateral forces resulting from the tensioned tension members inside the belt, which cause the timing belt to run off. In this manner, the friction forces in the drive are considerably reduced which leads to improve positioning properties.

Additional the new BRECOFLEX® timing belts achieve a notably improved pitch stability. The deviation of the tooth spaces could be further minimized.

With the new generation of BRECOFLEX® timing belts, the user is offered standard products which unite outstanding properties, such as high power transmission, high rigidity, optimized running behaviour and high precision.

BRECO M: The BRECO® timing belt is manufactured in open length. The tension members are always arranged with parallel edges. Open length is required e.g. in linear transmissions. All tension members assume part of the load.

BRECO V: BRECO® timing belts are manufactured from open length material welded to endless belts. In the join area the half number of tension members assume part of the load. The use of endless joined BRECO® timing belts is preferred in the conveying technology to handle any centre distance.

Application areas

Open length for linear transmissionsRotary movements are converted into linear movements by linear transmissions. The BRECO® timing belt in its open length delivery form is preferably fitted to the machine part to be moved.

Joined belts for conveying drivesEndless joined timing belts without length limitation are available. The minimum length for various belt profiles, however, is to be taken into consideration. For special requirements in transportation timing belts are coated or manufactured with flights/profiles.

Timing belt lock for BRECO® timing belt

The BRECO® timing belt lock for the timing belt types AT10 DC and T10 DC is mainly used for low load drives but extensive assembly work. The lock offers substantial savings in work and costs where, for design purposes, the timing belt can only be joint to an endless belt after being inserted in the machine. It can also be used as an „Emergency belt“ to bridge downtimes as a result of malfunctions and belt failures. When using the lock for timing belts with flighted profiles, take a minimum profile spacing of 100 mm into account.

AT10 DC / T10 DC timing belt lock(pictorial schematic)

Ordering information

The lock elements on the belt rear are countersunk so that the elements are flush with the belt top edge. For this reason, the timing belt usedmust be thicker than the standard BRECO® AT10 or T10 timing belt. Ensure that you specify the version as „DC“ when ordering an „AT10“ or „T10“ belt.

Tooth gap shapes

Timing belts are positive fitted drive elements. They work slippage-free with the respective synchronising pulleys.BRECO® and BRECOFLEX® timing belt drives can be optimised additionally for a movement transmission with a low flank backlash.

For some profiles and pitches, the SE or zero gap can be used for especially high requirements on the precision of the movement transmission. Please contact us for technical advice.

• Prerequisites for the application: Pitch matching between timing belts and pulley.

• Influencing factors of the pitch matching: - Pre-tension force - Meshing distance (ze) - Load rate (rotational speed, dynamic behaviour...) - Manufacturing tolerances

Timing belt guidance by flanges

Timing belts must be guiding to eliminate the lateral wandering-off effect. This is normally done by flanges.

Minimum lateral forces and low frictional losses can be resulted by the optimum arrangement of the belt guidance.

For this purpose, the following possibilities are available:• Timing belt guidance downstream of a large free span

length (infeed length (a) should not remain under 5 times belt width)

• Guidance at the drive pulley (to prefer for two shaft drives with short axis distance)

• Guidance of the pulleys with low power transmission (to prefer for multi shaft drives)• Guidance on the tension rollers - Tension roller arrangement in the slack span side - With arrangement on the flush belt side: consider minimum diameter with contraflexure - With arrangement on the meshed belt side: Length of angle of wrap, min. 3 teeth - With changing rotational direction preferable in the

span length centre - Condition: Minimum span length (a) between

tension roller and pulley should not remain under 5 times belt width

• Ensure high axis parallelity and flush alignment of all pulleys to achieve optimum guiding features.

• For cost reasons it is possible to fit flanges also to the smaller pulley taking the functional reliability into consi-deration.

Tooth gap shapes, see example T10

Normal gap SE gap 0 gap (low-backlash)

The utilisation of BRECO® and BRECOFLEX® timing belts with bifilar tension member arrangements is the ideal prerequisite for an optimal belt guide.

Angular drive with 3 axes

IT

Angular drive with 2 axes

BRECOFLEX® timing belts can be applied as angular drives. Take into consideration that the timing belt can only be crossed (twi-sted). Eliminate the wandering-off effect.

IT/b ≥ 20b = Belt widthIT = span length

Fadm : Admissible tensile force

FU : For the drive remaining circumferencial force

FS : Tensile force due to crossing

With crossed timing belt applications the outer tension members suffer a higher elongation as the inner ones. Due to the larger elongation in the edge zone the permitted proportional circumferencial force for the belt in the tension members is reduced.

No power reductions or constructive special means are necessary at a ratio of IT / b ≥ 20. At a required ratio of IT / b < 20 please contact our technical department for advise.

Safety factors

The width of a timing belt is correct when the permissible values for tooth shear strength, tension cord strength and flexibility are not exceeded under unfavourable operating conditions. In our catalog, load limits are stated which have been reliably proven and confirmed by bench tests and results obtained in practice. A safety factor is only required for drives with transmission into higher speed.

It is important, that the unfavourable load types occuring in the drive are known resp. correctly estimated by the engineer. With a positive fit transmission, even short-period overloads act via the timing belt being the drive member. Some instructions to this issue:

Rated operationDesign timing belts for the operating condition of the rated load. The rated load is the operating condition at which the drive should transmit the torque or the power at rated speeds under normal conditions.

Start-up characteristicsa) Drive side: The max. torque of the drive machine under start-up conditions is to be taken into consideration.

The start-up torque, e.g. for three-phase squirrel cage motors amounts to 2 to 2.5 times the rated value.

b) On the drive side: If necessary, „initial torques“ affective to the drive part timing belt are to be taken into consideration under start-up characteristics.

Check load case a) or b) with rotational speed n=0.

BrakesIt might have to be defined whether braking leads to loads which fully act via the timing belt and possibly exceed the type of load produced by the rated operation or the start-up characteristics. In the braking operation the torque reversal is to be taken into consideration.

Unevennesses (variations, impact shocks)In addition to the rated load, superimposed vibration and impact shocks could act on the timing belt as the transmission member. For the illustrated example, increase the calculated belt width by the factor of 1.3.

Moments of inertiaMoments of inertia and/or centrifugal masses in the drives generally create a uniform running behaviour. Depending on the acceleration and deceleration characteristic it has to be differentiated and checked whether the moments of inertia create an additional load on the timing belt.

Step-up transmissionThe following safety factors are to be applied for step-up transmissions:

In the braking operation may occur a torque reversal and the reduction can change into a step-up transmission.

Pre-tension force

Pre-tension is intended to guarantee a minimum tensioning force at the slack span side to ensure smooth tooth meshing into the driven pulley.

Generally, the pre-tension should only be set as high as necessary. The necessary pretension force of the spans FV de-pends on the max. circumferencial force FU , the belt length LB (number of teeth zB) and the drive configuration.

The recommendations shown in the table refer to the pre-tension force setting per span.

In every case, the tension cord strength is the top limit of the span load. Take into consideration that especially with multiple-shaft and linear drives, an addition of the pre-tension force and the circumferencial force in relation to the load span force is to be expected.

Influence variables

Stiffness of the beltFriction forces created by the interaction of the tooth mesh (especially at the slack span) intensify the span forces, which in turn increase the degree of elongation. This influence may lead to the slack span tooth mesh butting against the driven pulley, thereby causing the belt to jump.Elongation being directly depending on the belt stiffness, the high stiffness of the steel cord tension members permits a comparably low pre-tension.

Circumferential forceThe circumferential force acts in proportion to the elongation of the load span, i.e. excessive slackening of the slack span can be counteracted by a pre-tension matched to the circumferential force.

Belt lengthBelt elongation resulting from the effect of the circum-ferential force and the friction forces is also approximately in proportion to the belt length. Therefore, the tendency of running up or jumping is considerably influenced by the belt length. Even under high circumferential forces with the resulting friction forces, a very short timing belt will elongate to only a small degree, so that even when subject to low pre-tension forces there will be no danger of running up or jumping of teeth. On the contrary, with short timing belts circumferential deviations of the pulleys could cause heavy pre-tension fluctuations and, as a result, extreme peak values.

Proportion of the span lengthsEspecially with multiple-shaft drives the load span is often markedly longer than the slack span side. For this reason, a slight elongation of the load span results in a very unfavourable slack on the span side. Therefore, the pre-tension force of spans of such gearings should be higher than the circumferencial force.

Precise transmission of movementThere is a high transmission accuracy possible in the reverse operation with BRECO® and BRECOFLEX® timing belts, when the span pre-tension forces are selected in the same size of the circumferencial force.

Consequences of faulty pre-tension setting:

Too low pre-tension• The teeth of the slack span side run up on or override

the teeth of the driven pulley• Wear on the faces caused by the friction force during

meshing• Forced breakage by excessive elongation due to full

overriding

Excessive pre-tension• High bearing load of the shafts• Reduction of the transmissionable power• Wear and tear at the belt tooth

General information

Design• In the transmission configuration, design at least one

adjustable axis, plan one adjustable tension roller (not spring-loaded) for fix centre distances

• The bearing has to be absolutely rigid• Note the importance of a parallel run and flush

alignment of the synchronising pulleys Transport/storing• Upon receipt, unpack the timing belt immediately and

store in circular position in a dry place at room temperature

• Do not bend

Measuring with frequency measuring meter

The intrinsic frequency of a vibrating belt span can be mea-sured by means of various Mulco belt tension measuring meters. The pre-tension force of the span can be calculated from the measured intrinsic frequency:

FV = 4 · m · lT2 · f2

The corresponding intrinsic frequency can be calculated, if the pre-tension is preset:

Mounting• Fit timing belts on the pulleys when slack without exer-

ting any force• Exert no force when fitting with fix centre distances if

necessary, fit together with synchronising pulleys• Apply pre-tensioning force according to the chapter

„Pre-tension“• Secure adjustable axis against sliding• Do not clamp the timing belt between the flanges

Operation• Protect the drives against dust, dirt, hot surrounding

media as well as acids and lyes • Take into consideration the ambient temperatures

(see characteristics of polyurethane timing belts)

The recommended minimum number of teeth and/or the minimum diameter for a malfunction-free operation depends on the selected belt type. Take especially into consideration that the minimum number of teeth and/or the minimum diameter is higher when using a belt arrangement „with contraflexure“ (e.g. due to a tension roller).

The selection of the minimum number of teeth and/or mini-mum diameter of the pulleys as well as tension and return rollers is based on a large number of different parameters. In the applications of the belt is to taken into consideration the belt versions and the flexibility of the tension members.

1. Tooth shear strength Specific tooth shear strength

The specific tooth shear strength depends on the rotational speed. The maximum specific tooth shear strength is the limit load the belt tooth can bear in continuous operation. The values are stated in tables for each timing belt type. The timing belt drive is correctly designed, when not exceeding the admissible tooth shear strength. Generally, a special safety surplus is not necessary, see chapter „Safety factors“.

The high specific tooth shear strength of the ATP profile, for example, is achieved by the optimised force and load distribution. The effective force is distributed to two tooth faces.

The working loads can be distributed the more effective the more belt teeth are meshing in the pulley. Maximum number of teeth in mesh (BRECOFLEX® timing belts): zemax=12

Due to the high pitch accuracy of BRECOFLEX® timing belts generally, it can be calculated with 12 belt teeth in mesh, should the number of teeth in mesh be respectively high enough.

The timing belt is designed correctly, when the maximum admissible tensile load in the steel cord tension members is not exceeded under operation conditions. The table values for Fadm refer to the constant loading.

Transport timing belts are to be designed preferably as head drive. The goods to be transported can consist of one or more individual loads. A lot of individual loads can be seen as line load.

From the overall transport load, the required haul-off force or the circumferential force FU for the drive pulley assemblies can be derived:

Circumferential force in the drive pulley station FU [N]Mass of the items to be transported m [kg]Friction factor of the timing belt in relation to the bed plate µ

As friction factor µ (slide friction), the following values can be assumed:

Steel/PUR 92 Shore A 0,6 - 0,7Steel/PAZ 0,2 - 0,4 PE/PUR 0,3 - 0,4

In general, friction factors show large ranges. Trials should be carried out, if necessary. Information without obligation.

A dimensionally stable surrounding structure is to consider.

Surrounding structure

Low friction and low dead weight is to be aspired for all assembly modules assuming part of the movement. The surrounding structure is to design dimensionally stable. Generally, BRECO® AT and ATL timing belts as open length are to be clamped on the moving linear technology using clamp plates. BRECO® AT and ATL timing belts permit a rotational to linear translation of movement with continous accuracy.Due to the high pitch accuracy between belt and pulley meshing the load distribution is distributed equally to the tooth faces in mesh on the drive assembly pulley and that produces a high performance and accuracy. The choice of materials for the belt and pulley is especially suitable for bi-directional drives. The distance of travel per pulley revolution is defined with the selection of the pitch and the number of teeth of the drive assembly pulley. For the linear drives are three design versions available. (Please note chapter „Belt guidance“)

Construction features

The most common output movement of electro-mechanical drives is the rotational movement. For the technical designer is the timing belt an ideal link in the kinematics. The timing belt transmits reliable, fast and directly rotational movements into linear motions. Travel speeds up to 10 m/s and any centre distances are possible. Within linear motions low position deviations are often required, e.g. in the handling technology (high precision of repeatability). We recommend our product range of BRECO® timing belts with the profiles AT and ATL. These polyurethane timing belts are designed and optimised for linear drives. They stand out for dimensionally stable teeth and stiffness of the belt spans. Under extreme load and after a short run-in time, the pre-tension of the belts might slightly reduce by the tension members settling, making a once-only re-tensioning of the timing belt unavoidable. No post-elongation of the tension members is to be expected in continuous operation.

The timing belts are temperature resistant with ambient temperatures from -30°C to +80°C. Applications close to the limit temperatures (<-10°C and >50°C), however, might require adapted dimensioning. In this case please contact your distri-bution partner.

This catalog has been compiled to especially meet designers requirements. In this catalog you will find both the delivery range and all technical data required for the dimensioning linear drives. Take into consideration corrections to the admissible load values, in case of deviations from the standard.

Construction

BRECO® timing belts are constructed of wear resistant polyurethane and high tensile steel cord tension members. Both materials combined form the basis for dimensionally stable and reliable BRECO® timing belts. An additional nylon tooth facing results in a low-friction timing belt with high performance.The BRECO® timing belts is manufactured without length limitation. The steel cord tension members are arranged with parallel edges. The preferred delivery form is in rolls of 50 m or 100 m.

A linear drive is pre-tensioned correctly, when under maximum effective tangential force Ftmax (from acceleration and braking) the slack span side of the belt stays tight. A mini-mum pre-tension force is to be considered:

The highest span forces FTmax are to be expected within the tight span side, when both pre-tension force FTV (static) and tangential force Ft (dynamic) acting together.

The admissible tensile load FTadm has to show always safety factors to the max. occurring span force FTmax in the timing belt.(FTadm see Technical Data)

The static centre/axis load FAsta act within the stand still or under no-load conditions. FAdyn is a value depending on the effective circumferencial force.

The mass of a pulley and/or tension roller is calculated in relation to:

The reduced mass mZred of a pulley and/or tension roller is an equivalent mass with equal load bearing to the effective line of the timing belt, the same as the rotational solid to the rotational axis.

How to proceed

General kinematics

Coarse designaccording to mass and acceleration

The drive station

The above mentioned equations can be used to comprehensively compute BRECO® linear drives. The type of the individual examinations depends on the task. If necessary, request technical support from our sales outlets.

If the movement sequence of the linear drive has to be timed, we recommend to proceed in accordance with the linear movement values of the equations (3).

Generally, the mass of the linear slide mL and the acceleration a represent the decisive values for the design of linear drives. On page 152 the belt type and timing belt width can be determined, based on mass and acceleration after the selection diagram.In conjunction with the coarse design, we recommend to adopt the pulley dimensions (as a provisional measure). Note the permissible minimum number of teeth or minimum diameters.

The required tangential force Ft in the drive pulley assembly has to be determined accor-ding to equation (4). By provisionally assuming the pulley size, it is possible to calculate the attendant drive torque M according to equation (2) for the drive pulley assembly. In how far the calculated torque M can be harmonised with the torque sequence of the motor, depends on the type and selection of the drive motor. The selection of the motor also depends on the desired servo and positioning tasks. Once the drive motor has been decided upon, the actual torque sequence of the motor has to be taken into consideration for the further precise design of the timing belt.

The tensioning station can be mounted at any position on the timing belt. Values for cspec see technical data.

(formula 11)

Elasticity c [N/mm]

Linear systems show a variable elasticity. The elasticity behaviour of the linear slide and/or linear bed depends on the length proportion L1 and L2. That means: Each individual position of the linear bed has its own elasticity.The elasticity shows a minimum cmin, when L1 and L2 are equal in length.For this case the following relation is valid:

For technical structures, avoid compatibility of fe = f0 (resonance).Note: In linear drives, the natural frequency fe is in general considerably higher than the excitation frequency f0 of the drive, in which case no resonance is to be expected . We recommend a special examination, if necessary, where stepping motors are used. Measures in the event of resonance: Increase the stiffness of the timing belt by choosing a larger belt width.

User information Part of the offered formulae contain simplified assumptions.E.g. calculation of the positioning deviation according to equations (12) and (13): The elon-gation behaviour of the tension member is also taken into account in the area of the pulley angle of wrap. However, the elasticity of the belt tooth has been neglected.E.g. the vibration behaviour according to equation (14): Only the vibrating mass m of the linear slide mL is taken into account. The vibrating mass of the timing belt, the pulleys as well as the retroaction of the elasticity to the surrounding structure have not been taken into consideration.

For this reason, we point out that corresponding deviations have to be expected, depending on the drive geometry selected.

Check the tensile loads for the calculated belt width, which become effective due to the pre-tension force FTV according to formula (7) and the overlapping tangential force Ft accor-ding to formula (8). The max. permitted tensile loads according to formula (9) must not be exceeded. If necessary, select the next larger belt width.

Check of tensile load

Safety factors Special additional safety factors are not necessary for the BRECO® timing belt. When, however, in addition to the maximum tangential force Ftmax are to be expected unevennesses, variations or impact shocks, which are not yet cosidered in the design, any additional safety factors can be added to the belt width.

Accuracy in the rotational to linear translation of movement

The BRECO® timing belt transmits rotational movements into the corresponding linear motions via the pulley of the drive station. The procedure can be repeated as often as required and is a continous operation with BRECO® timing belts. Deviation from the linear line can occur due to different forces and tolerances. The following is a description of causes and measures to be taken.

1. Precision of repeatability

The term repeatability of a linear drive implies the capability of regaining a position once accessed under the same conditions. In linear systems, repeatabilities of notably less than +/- 0.1 mm per metre of path travelled can be achieved with BRECO® AT timing belts. Prerequisite for a consistent repeatability is the retaining of the minimum pre-tension force according to the equation (7).

2. Positioning precision The term positioning precision of a linear drive is the capability to convert the turning angle of the pulley into the attendant setpoint linear path via the timing belt. The achievable actual linear path depends on the active forces and of the tolerances of all assembly groups involved in the sequence of movement. Measures: Individual measures according to the following points 3 - 8 are to be applied, depending on the dominating values.

3. Stiffness / force- extension behaviour

If varying forces act on the linear unit, a correspondingly different elongation becomes effective. The corresponding “specific elasticities” are indicated in the Technical Data for steel cord tension members.Measures: Plan a wider timing belt to keep the elongation small. The positioning deviation resulting from the elongation behaviour can be calculated with the equations (12) and (13). A dimensionally stable surrounding structure is to consider.

4. Inverse fault

5. Length tolerance Pitch deviation

6. Pitch faults

7. Eccentricity fault Centre offset

8. Ambient temperature Elongation under heat

When a linear position is moved to from a different direction, an inverse fault could occur in relation to the desired position. In other words: If the forces acting on the linear unit inverse, an inverse fault could occur. Measures: Design linear guides and the entire system such that low friction occurs. Design the pulley of the drive pulley assembly with a narrower tooth gap or with a „0“ tooth gap. Normal requirements with regard to the positioning precision are reached with the standard tooth gap. For the use of special tooth gaps, please ask for our technical support.

A length tolerance in the timing belt leads to a pitch deviation. In this case, all pitches remain identical in relation to each other. Once installed, amongst others, a length tolerance/pitch deviation depends on the pre-tension applied. The length tolerance/pitch deviation is available in pre-defined ranges, due to the production method.Measures: Use BRECO® timing belts in the minus tolerance range, and pre-tension to the setpoint dimension once installed. Ask for our specialist support.

The term pitch faults defines irregularities of neighbouring pitches. Pitch faults have no cumulative effect within one belt section.Measures: Design the pulley of the drive pulley assembly as large as possible. The larger the number of teeth meshing in the pulley, the more efficient pitch errors are suppressed.

The eccentricity fault and/or centre offset of at least one pulley or tension roller involved can lead to an irregular movement in the linear system. This type of fault should be assumed when sinusoidal movements occur in the linear movement sequence.Measures: Check the concentric precision and the centre offset. Reduce the tolerance range, if necessary.

The linear elongation under heat of the BRECO® timing belt with steel cord tension members shows the same values as the linear elongation under heat of a surrounding steel structure. No change of the pre-tension force is then to be expected. In the case of a surrounding aluminium structure and a rise of the ambient temperature, a slight increase of the pre-tension can be expected. The attendant linear path changes with the linear elongation behaviour under heat of the surrounding structure.Measures: The influence of elongation under heat in the belt and also in the surrounding structure are minor. Temperature influences only need to be taken into account in exceptional cases.


For the calculation of the belt width the actual torque characteristic of the drive motor - from drive or brake - is to be used. At first the maximum motor torque according to formula (2) is to be converted to the respective circumferencial force FU. From the calculated tangential force the minimum width of the timing belt, according to formula (1) can be calculated.

The result of the calculated belt width (b in cm) is the required belt width for transmit the tangential force Ft via the meshing teeth from the pulley to the belt (or reverse). The calcu-lated belt width is to be rounded-up to the next larger standard belt width.
